Joe Sexton is a Partner with Galanda Broadman, PLLC. Joe focuses on tribal sovereignty issues, working primarily on environmental and cultural resources matters, advocating for enrolled members in disenrollment defense and civil rights plaintiff cases, economic development for tribal governments and individuals, and complex Indian Country litigation. Joe has also successfully represented individual tribal members in catastrophic injury and wrongful death cases, securing favorable settlements.

Before joining Galanda Broadman, Joe worked in-house for a tribal government.  While working in-house, Joe developed and enhanced tribal government programs, including a motor vehicle registration program. He also negotiated the purchase of tribal lands, and successfully fought in courts and administrative forums to protect his client’s tribal sovereignty, the rights of his client’s constituents, and his client’s threatened cultural resources.

His experiences before practicing law—including service in the United States Marine Corps and working as an intern in Bosnia and Herzegovina— equipped Joe to thrive in diverse communities, work efficiently and effectively under pressure, and relentlessly pursue his clients’ objectives. 

After law school, Joe worked for Williams Kastner, a medium-sized Seattle law firm, where he represented businesses and individuals before federal and state courts, often-times securing summary judgment rulings in his clients’ favor and achieving favorable settlement results at mediation.

Joe has been named to the Super Lawyers Washington Rising Star list from 2016 to 2018.
